问题
I have a C# application that is using wndproc to get a message for a right click to the taskbar, but I also need to use a left click to the taskbar so that I can minimize my form. The message value for right click on taskbar icon is WMTaskbarRClick = 0x0313. Does anyone know what the message value is for left click on taskbar icon?

FWIW: I don't know that you should minimize a form when the taskbar is left clicked. The default behaviour should be to minimize a form whose taskbar button is left clicked and Windows handles that for you.
